First I want say that this mod has been done before but I don't think like this!
This is what you have when you start.
We are going to be modding that piece that the arrow is pointing at (AKA pressure switch)
Start by getting a screw driver or pencil put it under the pressure switch a lift up.
It's super easy to get out!
Now take out your pressure switch and use a pocket knife/drill/ and make room for the pressure switch.
Then put your pressure switch in like this!
Then take the cover off and your done!
